Bileski Christmas Stamp Collections. Comprehensive Kasimir Bileski prepared Christmas stamp collections for the years 1964, 1965, 1966, 1967, 1971 and 1972. All neatly mounted by the collector on two different styles of album pages. The material includes mint and used singles, blocks and panes, regular and Winnipeg/Ottawa tagged stamps as well as cacheted First Day Covers. Bileski was for decades the undisputed master of philatelic marketing and quality offerings like these. Estimate
